Factors associated with patient-reported outcome measures in knee osteoarthritis: A cross-sectional community-based study

Knee pain resulting from osteoarthritis (OA) often leads to functional limitations and disabilities, significantly affecting an individual's quality of life. This study aimed to explore the factors associated with patient-reported outcome measures in knee OA. A cross-sectional study was conducted using data from the Community Oriented Program for Control of Rheumatic Diseases (COPCORD) study in Jakarta. A home-to-home survey using multistage stratified random sampling was conducted involving subjects who met the clinical criteria for knee OA. Data collected included demographic information, body height and weight, history of injury, degree of work activities, presence of body aches and joint pain, and comorbidities. Patient-reported knee outcomes were assessed using the Knee Injury and Osteoarthritis Outcome Score (KOOS). Bivariate and multivariate analyses were performed to identify factors associated with KOOS and its subscales. A total of 71 subjects meeting the clinical criteria for knee OA were included in the analysis, with a mean age of 54.54±9.97 years. Cardiovascular disease was significantly associated with overall KOOS scores and all five subscales. Additionally, OA subjects with a history of knee injury scored worse specifically on the KOOS quality of life subscale. Cardiovascular disease and a history of knee injury were significantly associated with worse patient-reported knee outcomes among knee OA subjects. Future studies involving more cities are recommended to confirm these findings and provide more robust results for the Indonesian population. El dolor de rodilla resultante de la osteoartritis (OA) a menudo conduce a limitaciones funcionales y discapacidades, afectando significativamente la calidad de vida de un individuo. Este estudio tuvo como objetivo explorar los factores asociados con las medidas de resultados informados por los pacientes en la OA de rodilla. Se realizó un estudio transversal utilizando datos del estudio del Programa Orientado a la Comunidad para el Control de las Enfermedades Reumáticas (COPCORD) en Yakarta. Se llevó a cabo una encuesta de casa en casa utilizando un muestreo aleatorizado estratificado por etapas múltiples, involucrando sujetos que cumplían con los criterios clínicos para la OA de rodilla. Los datos recogidos incluyeron información demográfica, altura y peso corporal, historia de las lesiones, grado de actividades laborales, presencia de dolores corporales y articulares, y comorbilidades.
